http://vistaprint.com/ is offereing 250 free business cards. You just need to design it and pay ~$6 shipping. They try to upsell you pretty hard, but you can get it at this price.
I just ordered some for my Baseball Lessons. On the back is an ad for vistaprint, but for a few dollars they will remove it. So, for under ~$10 USD you get 250 customized business cards. There are 40 styles to choose from.
I thought some of our budding entreprenuers might like to check it out.
There is also a 21 day processing time period for the free cards. But, guess what? You can pay to get them faster!
